At 1007 hours, Lewes FD was dispatched, along with Millsboro FD, to assist Indian River FD with a working structure fire in Pot-Nets Bayside.  First arriving units from Indian River found a single-wide manufactured home with fire showing.  Indian River placed three attack lines in service, and an attack was made on the fire.  An initial knock-down was made quickly, but full control was made more difficult due to some structural collapse issues.  No injuries were reported at the scene.  Engines 82-1 and 82-2, Tanker 82-4, and Command 82-8 responded to this alarm.
